+ChangeLog:
+
+2002-02-25: bclary - modified xbDebugTraceOject to make sure
+ that original versions of wrapped functions were not
+ rewrapped. This had caused an infinite loop in IE.
+
+2002-02-07: bclary - modified xbDebug.prototype.close to not null
+ the debug window reference. This can cause problems with
+ Internet Explorer if the page is refreshed. These issues will
+ be addressed at a later date.
